| Abstrakt: | In this present paper, we introduce two new subclasses HkΣ (α, δ, λ, µ, σ) and HkΣ (β, δ, λ, µ, σ) of normalized analytic bi-univalent functions defined in the open unit disk and associated with generalized differential operator. Further, we obtain bounds for the second and third Taylor- Maclaurin coefficients of the functions of these subclasses. Also, we obtain some consequences of results obtained. [ABSTRACT FROM AUTHOR] |
